Final answer:
The nurse's precaution reducing the risk for potential infection is likely related to monitoring for increased redness, swelling, and pain after treating a cut or abrasion to prevent an infection from developing and causing more severe health issues.
Step-by-step explanation:
The question posed seems to concern a healthcare or medical practice related to preventing a potential problem due to a nurse taking precautionary measures. If the precaution referred to is about watching for increased redness, swelling, and pain after a cut or abrasion has been cleaned and bandaged, then the potential problem that it is intended to mitigate is most likely infection. These signs are typical indicators that an infection may be developing, which if left unchecked, can lead to more severe complications. Measures to monitor and address these symptoms help ensure proper healing and prevent skin infections from worsening or spreading.
It is important to note that the other options listed (deep tissue injury, hypothermia, and skin discoloration) are associated with different precautionary measures and are less likely to be the concern addressed by the surveillance of these particular signs of wound healing.
